Videos of the tornado that tore through Oklahoma Monday, devastating the town of Moore, are flowing into social media sites like Twitter and YouTube.

Below are a sampling of some of the more impressive views of the killer storm.

This video shows just what an EF-4 storm is capable of. Roofs are gone, homes are flattened. A chilling warning was given by the National Weather Service, "You could be killed if not underground or in a tornado shelter. Complete destruction of neighborhoods, businesses and vehicles will occur. Flying debris will be deadly to people and animals."

Sometimes you get to see a happy ending. This woman was talking with a news crew when the dog she thought she lost was found alive.

Hailstones, some as large as baseballs, accompanied the storms that struck Sunday and Monday across the Great Plains. This video gives an impressive head-on view of one of the storms.

This video is from one of the local television stations. The meteorologist at the stations are credited with helping to make viewers aware of the situation and saving lives.

This aerial video of the destruction from the tornado shows the scope of the storm.

People spoke about their experiences during the tornado strike and their attempts to help rescue neighbors and strangers. More than 140 were treated at hospitals. Rescue crews searched through the night for survivors and victims.

A man driving from work caught this video from his car. You can see hail hitting on the road and hear the roar as he pulls over and lets his camera roll.
